Plant cultivation bed and plant cultivation block

Abstract

The invention provides a cultivation medium promoting germination of plants and growth of the seedlings while precluding the plant from suffering damage from insect pests. The cultivation medium comprises a particulate, granular or fibrous rubber. Particulate, granular or fibrous pieces of plant or soil can further be incorporated into the medium. Seeds of a plant are sown on the cultivation medium or mixed with the medium for cultivating the plant.

What is claimed is: 
     
       1. A plant cultivation block comprising: a plant cultivation bed comprising an air permeable bag, the air permeable bag containing a cultivation medium and seeds of a plant, the cultivation medium comprising a particulate, granular or fibrous rubber; and a box having the cultivation bed accommodated therein, the box being provided at an upper side thereof with a protective member having openings sufficient for the growth of sprouts, and formed at a lower side thereof with holes and downward projections for drainage and air flow.   
     
     
       2. A plant cultivation block as defined in claim 1 wherein the cultivation bed further contains particulate, granular or fibrous pieces of a plant and/or soil. 
     
     
       3. A plant cultivation block as defined in claim 1 wherein the box of one plant cultivation block is releasably coupled by an attaching member to that of another plant cultivation block as arranged adjacent thereto. 
     
     
       4. A plant cultivation block comprising: a box covered at an upper side thereof with a protective member having openings sufficient for the growth of sprouts and provided at a lower side thereof with a bottom plate having holes and downward projections for drainage and air flow, the bottom plate having an upper surface with an air permeable fabric affixed thereto; and a plant cultivation medium comprising a particulate, granular or fibrous rubber, along with seeds of a plant, the plant cultivation medium being stored within a space formed between the protective member and the bottom plate of the box. 
     
     
       5. A plant cultivation block as defined in claim 1 wherein the cultivation bed further contains particulate, granular or fibrous pieces of a plant and/or soil. 
     
     
       6. A plant cultivation block as defined in claim 1 wherein the box of one plant cultivation block is releasably coupled by an attaching member to that of another plant cultivation block as arranged adjacent thereto. 
     
     
       7. A plant cultivation block as defined in claim 4 wherein the box of one plant cultivation block is releasably coupled by an attaching member to that of another plant cultivation block as arranged adjacent thereto. 
     
     
       8. A plant cultivation block comprising: a box provided at an upper side thereof with a protective member having openings sufficient for the growth of sprouts and provided at a lower side thereof with a bottom plate having holes and downward projections for drainage and air flow; a lawn grass mat placed into the box with its grass side opposed to the protective member; and a plant cultivation medium comprising a particulate, granular or fibrous rubber, the medium being stored within a space formed between the grass mat and the bottom plate having an upper surface with an air permeable fabric affixed thereto. 
     
     
       9. A plant cultivation block as defined in claim 8 wherein the cultivation bed further contains particulate, granular or fibrous pieces of a plant and/or soil.
